[0002]

2. Description of the Related Art As portable combustion devices, gas stoves and hand warmers using petroleum fuel as an energy source have been widely used. But gas stoves are dangerous with open flames,
In addition, most of the heat energy is released into the atmosphere, and the heating efficiency is low. Hand warmers can only heat a part of the human body.

[0003] Therefore, heating clothes, mats, and the like having a battery and having an electric resistor distributed inside have been considered.
However, the current battery has a low energy density per weight and cannot supply necessary heat for a long time to heating clothes and heating mats. Also, if such an attempt is made to supply such time and heat, the battery becomes large and extremely heavy, making it unsuitable for carrying.

[0004] Therefore, a petroleum fuel having a much higher energy density than a battery or the like is heated by using catalytic combustion to heat a liquid such as water and circulate an appropriate temperature liquid through clothes to warm the whole. Heating clothes are disclosed in JP-A-4-34.
No. 7,450 (U.S. Pat. No. 5,282,740).

[0005] Heaters for heating clothes by using heat of combustion include warmers using fuel such as alcohol and charcoal, and disposable warmers using heat of chemical reaction between metal such as iron and an oxidizing material. Was. As a fuel-equipped combustion device, there is a cooking cassette stove equipped with a butane cassette cylinder. This is called a cordless appliance because there is no electric cord, and is used as a heat source for cooking.

[0006]

The conventional portable combustion device has a problem that it is heavy and large in volume. Above all, heating clothes using a combustion device, using a liquid such as water as a heat catalyst, and connecting a heated medium and a heat source with a tube have problems of being heavy and having little flexibility. I have.

[0007] Further, conventional cairo and the like cannot heat a wide area of clothes only by heating a local area. Cairo had to be removed from clothing to refuel with alcohol and charcoal, which was inconvenient. In addition, disposable warmers cannot be reused, and it is difficult to control the amount of heat during heating, and the warmers cannot be heated at a desired temperature.

[0008] Further, a cooking cassette stove, which is another combustion device, has an operating part, a fuel cylinder and a combustor integrated with each other, and can be used for heating clothes even if it is simply installed in the clothes. In addition, since the operation unit and the combustor were integrated, the combustion charge could not be controlled from outside the clothes, and the amount of heat could not be controlled while wearing the clothes.

An object of the present invention is to provide a comfortable temperature environment in clothing by heating the entire clothing by using a lightweight, compact and portable combustion device for clothing.

[0010]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is characterized in that a combustion device is attached to the back of the inside of clothing, and the heat conductor is extended in a direction perpendicular to the combustion device, thereby reducing the weight. It is compact and quickly and uniformly heats the inside of clothing, creating a comfortable temperature environment.

And a fuel tank 53 for storing the fuel of the heat source unit 50. The heat source unit 50 is separated from the control unit 51, the operation unit 52, and the fuel tank 53, and
It is attached to. The heat source 50 is attached to the heat radiator 57, and the heat radiator 57 is detachably attached to the inner surface of the clothes 54. The heat source unit 50 communicates with the control unit 51, the operation unit 52, and the fuel tank 53 via a flexible communication path 56. In addition, the heat source unit 50 communicates with an intake port 63 and an exhaust port 64.

In the garment 54, there is provided an in-cloth detecting means 55 for detecting temperature, humidity, etc., and a signal line for transmitting the temperature information detected by the in-clothing detecting means 55 to the control section 51. Connected by

FIG. 2 shows the details of the heat source section 50. That is, the fuel sent from the fuel tank 53 via the communication passage 56 is jetted from the fuel nozzle 57. The ejected fuel sucks the combustion air 58 introduced from the intake port 63 to become an air-fuel mixture and is burned in the combustion section 59. Combustion unit 5
The igniter 60 protruding into 9 ignites the air-fuel mixture in the combustion section 59. Reference numeral 61 denotes an outlet of the combustion chamber, and the exhaust after combustion is led to an exhaust port 64. Heated by the outer wall 62 of the combustion part 59,
As shown in FIG. 2, the outer wall 62 is attached to the heat radiating portion 57 so as to be thermally conductive, and the air warmed by the outer wall 62 and the heat radiating portion 57 convects in the clothes 54.
Heat circulates through the clothes 54 to some extent even in natural convection,
By circulating with a blower, heating can be more effectively performed. Igniter 6
0, It is good to use a battery for the power supply such as the blower.

FIG. 3 shows a cross section of the communication path 56. The communication path 56 includes a fuel communication path 65 and an operation communication path 66.
Are formed. The fuel flows in the fuel communication path 65 in a gaseous state. The operation communication path 66 is provided with an ignition wire or a control wire, but when both are installed, they are separated by insulating rubber so that sufficient insulation is provided.

FIGS. 4A and 4B are cross-sectional views of the heat source section 50 and the clothes 54, respectively, showing the state before and after the wearing, respectively. As shown in FIG. 4B, the heat source 50
The heat source mounting section 69 is provided on the clothes 54 side, and the clothes mounting section 68 is provided on the clothes 54, and the heat source mounting section 69 and the clothes mounting section 68 are engaged with each other, so that the heat source section 50 is mounted on the clothes 54. . Further, a mounting portion is similarly provided in the operation portion 52 and the fuel tank 53. At this time, there are provided a plurality of clothes mounting sections for mounting the operation section 52 or the fuel tank 53, so that the operation section 52 or the fuel tank 53 can be mounted at a place where the operation section 52 or the fuel tank 53 can be easily operated or stored.

When the operating section 52 is operated to supply fuel from the fuel tank 53, the fuel is supplied to the heat source section 50 through the communication path 56. The fuel is butane, propane, or a mixture thereof, and is stored in the fuel tank 53 in a liquid state. The smaller the fuel tank 53 is, the better it is for carrying, but the longer the burning time is, the better. Therefore, in the case of butane, the capacity is set to about 14 g.

The fuel supplied to the combustion section 59 is in a gaseous state, and the fuel ejected from the fuel nozzle 57 is supplied to the supply port 6.
The air 58 introduced through 3 is sucked into an air-fuel mixture, and when the air-fuel mixture is ignited, it burns in the combustion section 59 to generate combustion heat. Most of the generated heat is generated by the outer wall 62 of the combustion section.
The temperature of the heat-exchanged combustion gas decreases, and the combustion gas is discharged from the exhaust port 64.

The fuel is liquid at the time of storage and is vaporized as it leaves the fuel tank 4. At this time, the temperature decreases due to heat of vaporization. When the temperature is low, the speed at which fuel is ejected from the fuel nozzle 57 is low. However, when the fuel passes through the communication path 56, the temperature rises due to heat from the outside of the communication path 56, the temperature of the fuel becomes normal at the fuel nozzle 57, and the velocity of the fuel jetted from the fuel nozzle 57 increases. Sufficient suction is possible.

In order to prevent the conducted heat from coming into direct contact with the human body, it is covered with a heat insulating material such as fiber or heat insulating material. Further, a part of the heat warms the air on the outer wall 62 of the combustion part 59, and the air flows upward in the clothes 54 by natural convection, thereby warming the whole clothes. The amount of heat required for heating varies depending on the heat insulation state of the clothes 54, the outside air temperature, and the individual difference of the person wearing the clothes, but is about 50 kcal / h as a guide.
This is close to the amount of heat dissipated by humans. However, in the early spring, it may be smaller than this calorie, and a lot of calorie is required in a cold below -20 ° C.

When the heat source section 50 is worn on the back of a person wearing the clothes 54, the person feels comfortable even when warm.
Also, since there is a depression in the back above the waist, a space is created between the clothes and the human body, and heat is easily circulated throughout the clothes. On the other hand, when the operation unit 52 and the fuel tank 53 are mounted at hand, the operation is easy, and the remaining amount and replenishment of the fuel are easy. It is preferable that the operation section 52 and the fuel tank 53 be placed in a place where they can be easily stored except when the operation and the confirmation are performed. Therefore, a mounting section 67 is provided on the operation section 52 and the fuel tank 53. There are several places on the garment side, where they can be placed where both storage and operation are desired. Therefore, it is understood that it is preferable to install the heat source unit 50 away from the operation unit and the fuel unit. In particular, when operating, the operation unit 52 and the fuel tank 53 are preferably installed outside the clothes or in the pocket, and when stored, it is preferable to install them in the pocket or inside the clothes. On the other hand, it is more advantageous to dispose the heat source section 50 inside the clothing in terms of effectively utilizing heat. Operation unit 52
And the position of the fuel tank 53 changes, the communication path 56
Requires flexibility.

The positions of the heat source unit 50 and the operation unit 52, and the positions of the fuel tank 53 and the in-clothing detection unit 55 change. Therefore, the communication path 56 must be flexible or have a sufficient length. In addition, it must be strong against bending. Fuel communication passage 63
, Butane, propane, or a mixture thereof is used, and therefore, rubber and other materials having pressure resistance and flexibility are used. High-voltage electricity for ignition or an electric wire for controlling the controller extends in the operation communication passage 64. for that reason,
